Title: Shotgun Sequencing
Post by: adrii01 on Nov 17, 2013
In the shotgun approach to whole-genome sequencing (shotgun sequencing), random DNA fragments of a chromosome are sequenced. The fragment sequences are then assembled into a continuous sequence that represents the DNA of the entire chromosome.

What are the steps in the shotgun approach to whole-genome sequencing?

Drag the labels to their appropriate locations on the flowchart. Only some labels will be used.

1) multiple copies of the same chromosome are prepared

2) Chromosome copies are broken into 1-kb fragments

3) 1 kb fragments are cloned into plasmids

4) the plasmids are sequenced

5) A computer combines the fragment sequences There is no use for RNA (1-kb fragments are transcribed into RNA) in the Sanger method = full genome sequencing i.e. the shotgun approach.
